Parallel parking is a method of parking a vehicle parallel to the road, in line with other parked vehicles. Parallel parking usually requires initially driving slightly past the parking space , parallel to the parked vehicle in front of that space, keeping a safe distance, then followed by reversing into that space.
The parallel parking problem is a motion planning problem in control theory and mechanics to determine the path a car must take to parallel park into a parking space. The front wheels of a car are permitted to turn, but the rear wheels must stay aligned. When a car is initially adjacent to a parking space, to move into the space it would need ...
This type of car parking fits more cars per length of road (or curb) than parallel parking when a wider space is available, and is therefore commonly used in car parking lots and car parking structures. Often, in car parking lots using perpendicular parking, two rows of parking spaces may be arranged front to front, with aisles in between.
Attended car parks and garages frequently use double parking to maximize vehicle storage density. A driver who double-parks in an attended car park leaves the vehicle's keys with the attendant. If the driver of the blocked car returns first, then the attendant can move the blocking car so that the blocked car can leave.
In the 1930s, Walker invented a device which added a fifth wheel to cars to aid parallel parking. The extra wheel was mounted on the rear of the vehicle, at right angles to the rest of the wheels. When in use, the fifth wheel lifted the back of the car off its normal rear wheels, allowing the rear of the car to swing laterally. [2] [3]
Parallel parking usually benefits with starting close to the front car in terms of the sides, yet it starts from a far. However it ends up nicely, but to do so one can notice it does some gliding during the process that defies regular situations. It might be best to use a more accurate one. --f s 20:11, 16 January 2013 (UTC)
Automatic parking is an autonomous car-maneuvering system that moves a vehicle from a traffic lane into a parking spot to perform parallel, perpendicular, or angle parking. The automatic parking system aims to enhance the comfort and safety of driving in constrained environments where much attention and experience is required to steer the car.
In some cities, parallel parking adjacent to bicycle lanes is permitted. This puts the bike lane in the dangerous door zone , but angle parking eliminates this hazard. Compared to parallel parking, reverse angle parking often provides more parking spaces in a given length of street, though this will vary depending on site conditions such as ...
